Five cohesive clusters of isolates, corresponding to the named Vibrio species, were detected among the isolates analyzed by MLSA. Intraspecies similarities were ≥93.6%, while interspecies similarities ranged from 78.5% to 80.0%, with the exception of 86.7 to 87.0% similarities between V. parahaemolyticus and V. alginolyticus and 89.4 to 91.2% similarities between V. cholerae and the V. cholerae-like species. NA, not applicable.
